The Black DeathThe Black Death, also known as the Bubonic Plague, attacked Europe in 1347. The Bubonic Plague was one of several plagues that would attack almost all of eastern hemisphere. The last plague attacked a European city, Marseille in 1722. In 1347, the name "Black Death" or "Bubonic Plague"? was not used. At that time they called the plague the Plague, or the Great Mortality. As we can see, the Black Death has been around for around 650 years, and many are still unsure of the origin of this deadly plague. There are several explanations for the origins of the Black Death. The first comes from medieval writers who believe it began in China because they viewed China as a land of magical events. Others thought it came from earthquakes and fires. But we all know that these explanations are just myths. But many historians agree that the deadly disease came from infected rodents that migrated from the Middle East to the area between the Black Sea and the Caspian Sea. The plague then spread to merchants traveling the western trade routes (the approximate date given is around 1347). Then the disease spread from merchants to Italian cities along the Black Sea. The “Black Death”? the plague quickly spread along other trade routes. However, thanks to the quarantine, parts of Europe were saved from the disease. In the 14th and 15th centuries, the Black Death was not as severe as when it first appeared. Doctors and investigators began to notice patterns in which plague was most active and when it was “dormant.” They discovered that the plague was strongest in summer and absent in winter. Investigators also noticed that the plague was more prevalent in poorer, more populated cities. Governments have therefore put in place a system of quarantine and treatment of infected people. In the 16th century, quarantines were a part of life. Cities began to investigate anything suspicious. Travelers were required to carry health certificates proving they have not been exposed to the deadly disease. Towards the end of the 16th century it was impossible to leave the quarantine zones. Starting in the late 17th century, European countries created a border between Europe and the countries where the Black Death originated. Anyone who tried to cross the border without authorization was shot..
